An expanded view of an artist rendering of the 70-metric-ton configuration of NASA's Space Launch System (SLS), managed by the Marshall Space Flight Center in Huntsville, Ala. Launching astronauts on board the Orion Multi-Purpose Crew Vehicle, this vehicle will enable humans to explore our solar system farther than ever before, supporting travel to asteroids, the moon, Mars and other deep space destinations. NASA plans to launch an uncrewed test flight of this configuration in 2017.
